SuDS permeable, Resin-bound surfacing UV stable.
Paths, driveways and car parks.
LimeBound UV Stable Resin Bound System is a resin-bound aggregate surface for pedestrian and vehicular traffic which is permeable (SuDS, Sustainable Drainage System-compliant), decorative and functional, seamless and slightly flexible.
The open matrix allows water to drain through to the base, eliminating water ponding and allowing water to drain to planted areas or land drains. The surfacing may be applied to SuDS-compliant bases and sub-bases, reducing the impact of urban development on flood risk and allowing water to flow into watercourses. Edgings created from brick, stone, timber or steel should be installed to retain and protect the resin bound surfacing.
The system is a two-component mixture of the highest grade aliphatic and latest technology ingredients, which bind a range of selected decorative, kiln-dried aggregates. It provides an attractive porous surface, which is strong enough for foot and light vehicle traffic of up to 7.5 tonnes.
Resin and aggregate:
LimeBound Resin Bound Surfacing Resin is ultraviolet (UV)-resistant resin and will not yellow on exposure to UV light. The resin is formulated using aliphatic HDI, which will not deteriorate nor become brittle when exposed to UV light when tested to BS EN ISO 16474-3 method A.
The performance and appearance of the finished surface are dependent on the aggregate used (see LimeGate Solutions LimeBound mix blend swatch sheet for colour options). The aggregate blends have been designed to achieve strength, resilience, porosity and decoration.
